Antibiofilm activities of fluoride releasing restorative materials

Backround/Aim: The purpose of this in vitro study is to evaluate the antibiofilm and antimicrobial activities of 5 different restorative materials that release fluoride. Material and Methods: Five different fluoride releasing restorative materials [Riva Self Cure (SDI, Australia), Riva Light Cure (SDI, Australia), Riva Silver (SDI, Australia), Dyract® XP (DENTSPLY, Germany) and Beautifil II (SHOFU, Japan)] and one composite resin material (Grandio, VOCO, Germany) were selected for this study. A total of 48 specimens (8 of each) were prepared using Teflon molds (4.0 mm-diameter and 2.0 mm-thickness). The antibacterial and antibiofilm activities of the mentioned restorative materials on Streptococcus mutans were evaluated. The data obtained were evaluated by One-Way analysis and Tukey's Test (p<0.05). Results: As a result, no correlation was found in terms of antibacterial and antibiofilm activities of the restorative materials evaluated in the study. While the dental plaque (matrix) accumulation was detected at least on the Grandio resin, the materials with the least cell adhesion were Light Cure and Riva Self Cure since it showed antiadhesive properties for S. mutans. Conclusions: Although the highest antibacterial activity against S. mutans was detected in resin-modified glass ionomers, biofilm matrix (dental plaque) accumulation was mostly detected on these material surface in our study.
